Over 1 billion tracking attempts blocked - featured by Forbes: "Meet Lockdown, The App That Reveals Who’s Tracking You On Your iPhone" -March 2020 (Editors' Pick)

Lockdown blocks trackers and badware in all your apps, blocking an estimated 100 million trackers per month for over 300,000 people.

— Comprehensive Protection —
Lockdown has two privacy features: Firewall and Secure Tunnel VPN. Each feature protects you from different threats, creating the complete solution for protecting your personal data, browsing history, and sensitive connections.

FIREWALL — Blocks Hidden Trackers: The world's first on-device, open source blocker that stops ads, trackers, and badware in all your apps.

SECURE TUNNEL — Keep Your Data and Browsing Private: It's the no-logs, blazing-fast, privacy-first VPN. The only VPN to prove its Privacy Policy and be fully audited.

- Simple, one-tap to get protected against thousands of trackers for most users
- Fully customizable blocking for advanced users: block any domain / service
- Works for all apps, not just the browser
- Useful preconfigured block lists that are updated every week
- Blocking works "on-device" meaning it does all of its blocking without sending all your data to a third party server, unlike other blocking apps

- Hide your location and unique IP address with one tap
- Keeps you safe on public wi-fi hotspots and sites
- Stops spying from snoopers and your ISP or cellular provider
- Ultrafast with over a dozen regions globally

- Other privacy apps lie on their Privacy Policy and secretly sell user data, even if they promise not to
- To solve this issue, the Openly Operated certification requires apps to *prove* their Privacy Policy
- Lockdown is Openly Operated certified with a public 38-page audit report, and audited multiple times by security professionals
- View full OpenAudit Report:

- Open Source: Since firewalls have access to *everything* you do, it's critical that any firewall you use should be open source. Lockdown is 100% open source.
- On-Device: Lockdown does its magic on-device and doesn't connect to any servers, or third-party analytics, or anything else. This way, everything you do stays private to you.
- World's Simplest Privacy Policy: Here's the entirety of it (July 23rd, 2019) - "Everything Lockdown Firewall does stays on your device, so what you see is literally what you get, and nothing more or less, because that's the way it should be."

Stopped Working In Background..(UPDATE)

UPDATE: I figured out with some trial & error that this app will continue to block trackers in the background but only if you have the VPN “secure tunnel” activated in the app with “background app refresh” turned on. The “Firewall” must also be turned on. If you only have the “firewall” activated but not the VPN “secure tunnel”, it does not seem to block trackers like Facebook that collect data on you while you sleep. I’m adding one star. It would be great if they made the firewall work by itself in the background because I’d rather not use a VPN at home, but I can live with it for now. Overall, I really like this app & company and recommend this product.

1st review:
I’ve been using Lockdown for about six months now. At first, I thought it was amazing. It would block many add trackers like Facebook and Google, even while I slept at night. However, I noticed recently that those trackers stopped showing up in my “tracking log” each morning. “App Background Refresh” is turned on, but it makes no difference. Nothing seems to be getting blocked unless I am actively using my phone. This is a big concern, and I hope they can figure out what’s going on or I will need to start looking at other options.

Developer Response ,

Hi Mattie Pie, thanks for your reviews and comments. Sorry about the issue you're seeing - the app should definitely continue blocking trackers in both conditions that you described. We can't seem to reproduce the bug that you're describing, can you please reach out to so we can help you out?

It simply stopped working

After 3 weeks of the app it simply stopped blocking any trackers, I would go into the app and it would show the firewall is off and it would turn back on only to still not block any trackers whatsoever. It was working great beforehand but then it kept forcing me to connect to the vpn that I wasn’t subscribed to and it keeps connecting me to the vpn but since I didn’t pay for it my phone doesn’t have access to the internet on top of e firewall not working. Hopefully this gets addressed in the future because as of now this app is slowing down my phone.

Update: ok so I even got the vpn trial and I turned off low power mode and I turned background app refresh on and it STILL won’t turn on the firewall. What do I have to do to get it to turn on?

Great app…

I have been dealing with hacking issues for the better part of two years now…most of it being harassing and I do believe I know who it is, though I’ve been told time and time again there’s nothing I can do about it. Apple, isn’t any help, though they’ve confirmed I’m hacked. I do know my “hack” isn’t a hack. RT BUDDY (look it up) and I’m sure there’s more. I know I’m “geofenced” as my phone acts up when I’m on the move. I’ve changed phones, numbers, SIM cards…nothing changes. Since getting this app…I have regained about 85% control of my phone again. It does still get turned off from time to time…(remotely?). The program works. No doubt. I’m not confident the updates are actually updating…i do manually input blocks as I come across them. I could use more help, perhaps understanding my situation better. I’ve reached out with emails…no response as of yet. Again…this has given most of the control back to me, but I want more. More stars if customer support existed.
